Water Heater Replacement Cost Calculator

Estimate what it costs to replace a water heater — by type, from a standard electric or gas tank to a gas tankless or an efficient heat-pump water heater. The result splits the unit and install, shows the cost net of any rebate, and compares the typical price of all four types.

Defaults are typical US ranges — edit them to a real quote. A heat-pump water heater costs more upfront but uses far less energy, and often qualifies for a rebate (enter the amount you actually get).

A planning estimate, not a quote. Real cost depends on tank size, fuel type, code upgrades (venting, expansion tank, pan), and your plumber. Get a couple of quotes.

Frequently asked questions

A standard electric or gas tank water heater typically runs about $1,200–$2,000 installed (the unit plus labor). A gas tankless usually lands around $2,500–$4,500 because of venting and gas-line work, and a heat-pump water heater is roughly $2,500–$4,000 but uses far less energy. Your cost depends on tank size, fuel type, and any code upgrades. Enter your own unit and install price above for an estimate.
